Sprint Network Information Center

Following a nationwide multi-year overhaul, Sprint's 3G voice network and 4G LTE network, provide customers across the country with significantly better call quality and faster data speeds in more places than before.

Sprint provides 4G LTE service covering more than 270 million. Sprint 4G LTE offers peak wireless speeds of 25Mbps and is designed to greatly improve the performance of video and audio applications. Customers can expect to experience the following performance improvements:

  • Faster data speeds that enable instant Web access for news updates, HD viewing and game-playing, quicker video downloads and clear video chats.
  • Better signal strength when making a call or using the Web.
  • Fewer dropped calls for peace of mind when talking to friends, family or colleagues.
  • Improved voice quality with HD Voice, a Sprint standard for crystal-clear voice calls.

Sprint Spark, an enhanced 4G LTE service covering more than 125 million people, is built for data and designed to deliver peak wireless speeds of 50-60Mbps today on capable devices.  With its unique combination of network technologies, spectrum capacity and tri-band devices, Sprint Spark is designed to greatly improve the performance of video and other bandwidth-intensive applications. It enables stutter-free video chat on-the-go and mobile gaming that leaves lag behind. 
How Sprint Spark Works
Sprint Spark combines 4G FDD-LTE at 800 Megahertz (MHz) and 1.9 Gigahertz (GHz) and TDD-LTE at 2.5GHz spectrum. Sprint Spark’s spectrum assets, technology and architecture are designed to deliver a seamless customer experience via tri-band wireless devices. Tri-band devices, named for their ability to accommodate multiple spectrum bands, support active hand-off mode between 800MHz, 1.9GHz and 2.5GHz, providing data session continuity as the device moves between spectrum bands. 
Future Uses
  • Today Sprint Spark is delivering peak wireless speeds per sector of 50-60Mbps on capable devices, with the potential over time to increase the peak speeds a customer will experience to well beyond 100Mbps. Sprint Spark has the potential to unlock applications, content and services that have previously only been experienced on the desktop, bringing them into the wireless and mobile dimension.

The Sprint network also includes nationwide HD Voice, a Sprint standard for crystal-clear voice calls. It provides a fuller, more natural-sounding voice, plus noise-cancelling technology that virtually eliminates background noise from places like a busy road or crowded restaurant. [1]

Sprint Direct Connect
Another aspect of Sprint’s network is improvements to the Sprint Direct Connect push-to-talk service. Customers who migrate to Sprint Direct Connect experience three times the push-to-talk coverage compared to iDEN, along with international direct connect reach to Latin American countries, and 3G broadband data capabilities.
Corporate Responsibility
Sprint is committed to wireless recycling and the use of renewable energy in its networks, ensuring it does its part to incorporate corporate responsibility into every major touch point of its business. Sprint uses the phrase "corporate responsibility" to describe its approach to balancing its business objectives with its environmental, social and economic responsibilities. Sprint has been recognized for the following sustainability efforts:

  • Sprint ranked No. 3 on Newsweek's 2011 Rankings of America's Greenest Companies, up from No. 6 in 2010 and No. 15 in 2009, based upon environmental impact, green policies and performance, and reputation survey scores as of October 24, 2011.
  • Sprint has upgraded its network to use single, multi-mode base stations.
  • Sprint cell sites are more compact, more energy efficient and able to provide better coverage and call quality to customers compared to our prior network.
This will reduce Sprint's total energy demand and the company's carbon footprint. Sprint is the only U.S. telecommunications company to commit to reducing its GHG emissions by an absolute 20 percent by 2017.

Previous 3G and 4G Base Stations

New Multi-Mode Base Station

With a rip and replacement of its network equipment, Sprint has made substantial changes to the cell sites that power its wireless network. The top image shows Sprint’s former base stations, which required single, refrigerator-sized cabinets for each technology. Large black coaxial cables ran from each cabinet to the top of the cell tower, which has an inherent loss of signal. The new multi-mode base stations require less space. Other advantages include the ability for Sprint to use spectrum bands on multiple technologies, replacing coaxial cables with fiber that is not affected by signal loss and improved remote radio heads that replace less efficient radios.
Multi-Mode Technology
The implementation of multi-mode technology throughout the Sprint network:
  • Enhances service
  • Creates network flexibility
  • Reduces operating costs
  • Improves environmental sustainability
